National Academy of Sciences RDA and UL guidelines
are being published and results for adults will be put here as
I become aware of them. Children, and pregnant or lactating
women have different requirements. The notes are not necessarily
from the NAS.

RDA = recommended daily allowance for most people
AI = adequate intake estimate when lack of RDA data
UL = tolerable upper intake levels are set to protect the most
sensitive individuals
ND = not determinable due to lack of data
RDA & AI values are given in the form women / men.
Some difference may be due to weight.
